Oh botw by far!! I've had kind of a rough year and it was a much needed escape as well as being one of the most breathtakingly gorgeous, detailed and fun games i've ever played. I loved every character and every second of playing through it and exploring.... Though bayonetta 3 was announced so it could take that number 1 spot.
And honestly i'd say definitely give Skyrim a chance if you've never played it before! I'm a bit of an elder scrolls nerd (as any fans of the series can tell from my username) and its a great game with tonnes of stuff to do and things to see, it's great for replay-ability too since a lot of quests have various outcomes and its fun to see what happens if you try something different.
Im literally replaying through it on xbox these past few weeks and still enjoying it a lot.
